Abstract
An infrared imaging system is provided with a shutter assembly having an integrated thermistor. In one example, a device includes a shutter assembly. The shutter assembly includes a paddle configured to move between an open position and a closed position. The paddle is configured to block external infrared radiation from reaching a focal plane array (FPA) in a closed position, and pass the external infrared radiation to the FPA in an open position. The shutter assembly also includes an embedded thermistor configured to sense a temperature of the paddle when the paddle is in the open position. In another example, an infrared sensor assembly includes a first set of mechanically engageable electrical contacts for engaging with a second set of mechanically engageable electrical contacts of a shutter assembly electrically coupled with a thermistor through a conductive path. Additional devices and related methods are also provided.
